I am currently trying to create a landscape document using r markdown. Since I also want the header to be in landscape, I have the following mystyles.sty document:


which is called in the header of my main document:

title: "Transition Matrix Report for 2015-01-20"
author: "Paul Lintilhac"
date: "Monday, February 2, 2015"
      in_header: mystyles.sty

however, when I try to knit the pdf, I get the error:

 ! LaTeX Error: Option clash for package geometry.

See the LaTeX manual or LaTeX Companion for explanation.
Type  H <return>  for immediate help.

l.62 \usepackage

pandoc.exe: Error producing PDF from TeX source
Error: pandoc document conversion failed with error 43
In addition: Warning message:
running command '"C:/Program Files/RStudio/bin/pandoc/pandoc"     TransitionMatrix.utf8.md --to latex --from     markdown+autolink_bare_uris+ascii_identifiers+tex_math_single_backslash-implicit_figures --output TransitionMatrix.pdf --template "C:\PROGRA~1\R\R-31~1.2\library\RMARKD~1\rmd\latex\default.tex" --highlight-style tango --latex-engine pdflatex --include-in-header mystyles.sty --variable "geometry:margin=1in"' had status 43 
Execution halted

I have checked many forums online, and they all seem to say that this error occurrs because I have tried to load a package with options twice. But clearly this is not the case. I have checked line 62 in the tex document produced by r markdown, and it is the line after calling usepackage[landscape]{geometry}. Getting rid of the other packages in mystyles.sty has no effect, however, when I go to the top of the tex document, I can see several other packages that are getting loaded automatically, as you can see at the top of the tex document copied below:

\usepackage{fixltx2e} % provides \textsubscript



I get the same error if I remove any of these except for \usepackage{ifxetex,ifluatex} , which gives a different error.

What is going wrong here and how can I fix? Would really appreciate your help as I have been trying to get this stupid formatting correct for hours.



  • Extra comma?! \usepackage{,pdflscape}

  • thanks for the comment, but as I said, removing the other packages from mystyles.sty has no effect unfortunately.

  • Please post a single complete example that generates the error. We can't debug code we can not see. Start with a copy of the first 62 lines of the document and delete anything you can while still generating the error, then post the result. Feb 2, 2015 at 23:53
  • sure, I just posted the minimum code that produces the error. I now see that there is a conflicting import of the geometry package, but I don't know what to do because this code is being automatically produced by r markdown.

    If you run latex on a document that has two \usepackage with the same package, by any normal reading you loaded the package twice. it may be you used a tool to generate a bad document but to be honest that's off topic for this site. Feb 3, 2015 at 0:12

look like loading twice to me.

    thank you for pointing that out. I realize that it is being loaded twice, but I did not do that myself -- it is just happening automatically. Any advice on how to stop that from happening?

    @PaulNo idea sorry, I don't have experience of that generator so can't say whether you are giving it bad input, or it is doing it on its own so it's a bug. If you have access to the document preamble and can cause geometry to be loaded earlier, load it with all the options (I assume bottow is a typo for bottom by the way) then both the current \usepackage will be ignored without error as they are using subsets of the initial option set.

  • @Paul: Your editor saw something shiny, was distracted, and then it magically thought to call geometry with a varied number of options... yes, so says my crystal ball Jeffrey... More serious though: your error points to line 62 as being a problem, while the minimal code doesn't have 62 lines. Why is that?

    @Paul: As pandoc seems to load geometry you could simply write in your own style \geometry{landscape,width=15in,height=11.5in,top=.5in,bottom=.5in} to change the settings. Feb 3, 2015 at 9:50
